T0 aZZ whom it may concern:

Be it known that I, WELDING E. SMrriI, a citizen of the 'United States,residing at Monroeville, in the county of Huron and State of Ohio, haveinvented a new and useful improvement in Plowshares, of which thefollowing` is a specification.

My invention relates to an improvement in piowshares, consisting of anoffset or projec- Lion extending below the base of the plowshare toprovide against the wear and rounding up of the point of plowshares. Theprinciple of this offset or projection extending downward from the baseof the plow is that it provides a bearing directly at the point,whiehcauses the said point as it bears in the ground to wear thinner andsharper and hold to the ground, whereas a plow-point made in theordinary way with agradual dowuward pitch in use wears off more on theunder side than elsewhere and forms a rounded bearing,whieh eX- tendsbaekward from the point of the plowshare and prevents the plow fromclinging to the ground. It is therefore evident that less service or useis gotten from the ordinary piowshare than from one with my improvement.My improvement can be applied to any pattern of plowshare, and Ithereforedonot elaim any particular form of plowshare, excepting thepoint thereof.

tend one-eighth of an inch below the base of 40 the plowshare and toextend half an inch from the eXtreme point thereof; but the projeetionmay be placed at any other point on the base near the front end, so thatit extends to the front end and is adapted to proteet the nose of theplow from becoming Woru and rounded at the base of the point.

My claim for which I desire to secure Letters Patent in the UnitedStaiesisspecifically set forth as foliows:

A plowshare having an offset or projectiou on its base near the frontend thereof, said offset being at substantially a right angle at itsrear and extending to the extreme point of the share, substantially asshown and deseribed.
